brake box hook up

i have an 88 bronco, trying to hook up a brake box there are 4 wires. black is positive, white ground,red stop light, blue brake can somone help me with some info on hooking this up

What do you want to know exactly?The hot wire goes to a constant hot ie the battery,the ground obviously goes to the chassis,and the red and the blue go to the trailer plug.I am assuming that you are trying to hook up a 6 or7 way plug.If so then the plug should come with a detailed schematic of which wire goes where in the plug.
